The second model analysed is an extension of the Voters Model, where a third option is introduced. The original Voters Model describes an interacting particle system, where each voter can be influenced by one of its neighbours to change opinion. Following previous literature [1]}, a “centrist” party is introduced, and we assume incompatibility between pro- and no-vax view. All the transition probabilities have the same form: neutral clusters can persuade new users with a different opinion. Neutrality is not an indifferent position, but it is the support of a different narrative.
